Pretty sure NATO is going to be tested. After Ukraine. He'll build up his forces on a board and see what happens. If there isn't a NATO build up response, I worry he'll push over that boarder. Then what? We going to nuke him? No, we won't. Partly because Putin has got friends in high places in the West. If we didn't ready a traditional response, we could be salami sliced while we debate when to nuclearly respond.
